Hi Group, I am thinking about starting a service to repair the discs that always seem to fail due to scratches, embeded dirt, etc. I tried the low priced machines (<$200) and they just will not cut it for a business. Too expensive per disc and just do not do a good job, as they leave marks which makes backup impossible. Has anyone any experience with the high end repair machines? I see several in the $1500 and up range (way up!). I sure cannot afford to buy a lemon at these prices. Any info will be appreciated.
